Scale changes everything. What once was quite adequate for enterprise messaging can't scale to support "Internet of Things". We need new protocols, patterns and architectures to support this new world. This session will start with basic introduction to the concept of Internet of Things. Next it will discuss general technical challenges involved with the concept and explain why it is becoming mainstream now. Now we’re ready to start talking about solutions. We will introduce some messaging patterns (like telemetry and command/control) and protocols (such as MQTT and AMQP) used in these scenarios. Finally we will see how Apache ActiveMQ is gearing up for this race. We will show tips for horizontal and vertical scaling of the broker, related projects that can help with deployments and what the future development road map looks like.

5. DECOMPOSITION

6. #redhat #rhsummit
It worked on my machine
INT, STG, QA, and prod MIGHT BE
slightly different
Patching Prod may break my
application
Admins must guess what patches
apply to my application
My application has a different
lifecycle than the OS
Tracking libraries is risky
Modern applications have TONS of
NIH code
WHAT I BUILD, RUNS

7. CONTENT MATTERS

8. NOT ALL RAINBOWS...
APPROACH
Re-architecting for services is expensive
Not all applications are appropriate (yet)
DevOps isn't just tools
Silos like holding grain

10. WHAT IS THE CDK?
IT H ELPS YOU BUILD CON TAINERS
FROM THE WEBSITE
Red Hat Container Development Kit is a pre-built
container development environment based on
Red Hat Enterprise Linux to help you get started
developing container-based applications quickly. The
containers you build can be easily deployed on any
Red Hat container host or platform, including:
Red Hat Enterprise Linux, Red Hat Enterprise Linux
Atomic Host, and our platform-as-a-service solution,
OpenShift Enterprise 3.

11. WHAT IS THE CDK?
IT H ELPS YOU BUILD CON TAINERS
FOR REALS*
All the hard bits are setup already
Vagrant VM (hyper-v, vbox, kvm)
Docker
Kubernetes
OpenShift
You can use what you need
The technologies are setup mimicking
a light production deployment
HowTos, examples, and sample projects
available
Eclipse Integration
* /me dates myself

12. A BIT ABOUT THE BITS
DOCKER
A containerizing technology
Most popular
Geared to server applications
a number of others (e.g. flatpak, lxc,
rkt)
Runs as a daemon on Linux
Implementations on Mac & Windows
(usually) use a "hidden" Linux VM
​Very easy to use
​Dockerfile like a bash script
Building, tagging, and sharing
KUBERNETES
Orchestration for containers
Allows for indirection between services
Supports horizontal scaling of services
Supports clustering of servers to provide
service scalability
Declarative syntax allowing for more
flexibiluty
Combines Docker, Kubernetes and other
technologies to provide a complete
container platform
Provides a simple developer interface to the
technologies
Manages source to deployment lifecycle
automatically
Provides automatic application scaling
Unifies the management of the technologies
